[webkit-dev] "highlighting" a frame

[Simon Fraser]

I think what you really want is a border that shows *inside* the frame bounds, but over all of the content in that frame. There isn't really a mechanism to draw things like this currently.

I’ve attached a sample that shows the problem, if you’re curious to see what happens. If you look at the frameset.html page and mouse over the bottom frame that contains an iframe, the border style is the only one that shows up, and it is on the outermost frame in the frameset gets a border in addition to the iframe.

We have tried modifying the webcore html.css file adding in a :hover selector for frame and iframe that sets the border property, but this doesn't work correctly for embedded frames. When we test mousing over them it draws the border on the outer-most frame and not the inner frame which is what I want.
